added ios privacy manifests, fixed permission texts and updated the xcode project

Privacy manifests for the app, widget and share extension declare the
App Group UserDefaults access (CA92.1, 1C8F.1) required for App Store
submission. Photo library and camera usage texts corrected. Project
format and SwiftPM pins (Firebase 12.19) as updated by Xcode 27 / Flutter
3.47.

-Flutter-App für die Schul-Community: Webuntis-Stundenplan, Nextcloud Talk + Files, Custom MHSL-Backend (Breaker, Custom Events, Push).
+Flutter-App für die Schul-Community: Stundenplan, Ticker, Newsletter & Co. über das MarianumConnect-Backend, Nextcloud Talk + Files. Zwei Kontoarten: Schul-Konto (Schüler/Lehrer, Benutzername + Passwort) und Eltern-Konto (passwortlos per E-Mail-Code/App-Link, sieht die Stundenpläne der zugeordneten Kinder und erhält Elternbriefe, kein Talk/Files).

 **Settings:** Pro Feature ein Freezed-Modell unter `lib/storage/`, persistiert via HydratedBloc.
 
+**Session:** Die aktive Sitzung liegt in `SessionManager().current` (`lib/session/`). Nextcloud-Zugriffe nur über `SessionManager().requireNextcloud()` – Eltern-Sessions haben keine Nextcloud-Identität. Abmelden ausschließlich über `SessionLifecycle.signOut()`. Die Keychain-Keys in `SessionKeys` sind eingefroren (Bestandsinstallationen, iOS-NSE).
+
+**Mehrere Konten:** Die `SessionKeys`-Slots, der MC-Token und die Group-Keychain spiegeln immer das *aktive* Konto; inaktive Konten liegen im Tresor (`accounts_index` + `account_vault_<id>`, `lib/session/account_codec.dart`). Wechseln/Hinzufügen/Entfernen nur über `SessionLifecycle` (`switchTo`, `beginAddAccount`/`finishLogin`/`cancelAddAccount`, `removeInactive`), danach `AccountBloc.activated(id)`. Lokale Daten sind pro Konto getrennt (`AccountStorage`: eigene HydratedBloc-Box; der Request-Cache `CacheStore` folgt dem aktiven Konto mit eigenem Verzeichnis); nur die Settings liegen in der globalen Box. `SessionManager().sessionEpoch` steigt bei jedem Kontowechsel – asynchrone Arbeit prüft damit, ob ihr Ergebnis noch zum aktiven Konto gehört. Was ein Konto außerhalb seines Speichers hinterlässt (Tray, Push-Schlüssel, Downloads), räumt `SessionWipe` auf. Alle Pro-Konto-Blocs gehören in `AccountScope` – er wird per Konto-ID neu aufgebaut (samt `MaterialApp`/Navigator). Push ist nur für das aktive Konto registriert.
+
+**Rollen & Zuschnitt:** Views verzweigen nie auf Rollen. Module und Settings-Sections deklarieren `AccessRequirement`s (`nextcloud`, `guardian`; `AppModule.requirements`, `Settings._sections`); Views bekommen ein Subjekt + eine Policy, die an genau einer Stelle als pure Funktion aufgelöst wird (Vorbild: `TimetableSubject` + `TimetablePolicy.resolve`, `AbsenceFormPolicy`). `UserRole` nur für Anzeige/Policy-Ableitung.
+
+**Stundenplan:** Ein `TimetableBloc(subject: …)` für alle Fälle (eigener Plan, Fremdplan, Kind). Den globalen Bloc stellt `PrimaryTimetableScope` bereit und tauscht ihn beim Kindwechsel aus; page-scoped Fremdpläne nutzen `ScopedTimetableBloc`. Die Kinderauswahl (`ChildSelectionCubit`) ist modulübergreifend.
+
+**Elternbriefe:** Modul `parentLetters` (nur Eltern-Sessions, `AccessRequirement.guardian`): Lehrer-Mitteilungen aus MarianumConnect mit Gelesen-Status, Kenntnisnahme/Auswahl/Unterschrift pro Kind, Thread und Anhängen. Der Posteingang (`ParentLettersBloc`) ist global (Modul-Badge, Push-Refresh), ein Brief ist page-scoped (`ParentLetterBloc`). Ob und wie geantwortet werden darf, entscheidet der Server (`editable`); `ParentLetterFormPolicy.resolve` macht daraus das Formular. Push: Connect-Direct-Push `type: parent-letter`, Tap-Routing allein über `parentLetterId`. Alle Benachrichtigungs-Taps (lokal gerendert wie FCM) werden von `resolvePushTarget` (`lib/push/push_target.dart`) aufgelöst und in `NotificationTasks.openPushTarget` navigiert – neue Push-Ziele nur dort ergänzen.

+   `keychain-access-groups` (team-prefixed, **keine** App-Group). Damit greift das
+   `<TeamID>.*` der Xcode-Profile und Automatic Signing läuft ohne Portal-Änderung
+   durch (verifiziert: `flutter build ios --release` signiert Runner **und** NSE
+   mit `MY55VF3KPG.eu.mhsl.marianum.mobile.client.push`). Der frühere App-Group-
+   Ansatz (`group.*`) scheiterte an genau diesem Profil-Matching. Falls der
+   Keychain-Zugriff zur Laufzeit doch scheitert (Status `-34018` /
+   `errSecMissingEntitlement`), prüfen, dass Dart (`push_secure_storage.dart`) und
+   Swift (`AppDelegate.swift`, `NotificationService.swift`) **exakt denselben**
+   vollqualifizierten Group-String verwenden.
